GEZE Boxer ISM

The Boxer ISM system is designed for double leaf doors and is fitted with an integrated mechanical closing sequence control. The ISM guide rail is only visible when opening the door. When closing the moving leaf whilst both doors are open, the moving leaf remains in waiting position until the fixed leaf is closed and enables the moving leaf via the closing sequence control.

GEZE Boxer E-ISM

The GEZE Boxer E-ISM system is fitted with a guide rail that contains electromagnetic (E) hold-open devices for both door leaves plus an integrated closing sequence control and is only visible when the door is opened. When closing the moving leaf while the leaves are open and the E hold-open function is active, the moving leaf remains in waiting position until the fixed leaf is also closed and enables the moving leaf via the closing sequence control.

GEZE Boxer ISM-EFS

System solution for 2-leaf doors with integrated closing sequence control. A free swing function can be realised on the active leaf for 2-leaf doors thanks to the new Boxer EFS 4-6.

The system solution Boxer ISM-EFS for double-leaf doors provides, on the active leaf, the perfect combination of the new, integrated comfort hold-open function, which makes it possible to stop the door at the end of the free swing area, and the tried-and-tested GEZE "free swing" function, thanks to the use of the new GEZE Boxer EFS 4-6.

Locking the comfort hold-open function prevents unintentional closing, for example in the event of a draught, at the maximum opening angle. This has no effect whatsoever on the fire protection function – when this is triggered the door always closes safely, even when the hold-open function is engaged.

Furthermore, the "free swing" function enables people to go through the door with only a slight physical effort, in the opening or closing direction, once the door has been opened once, e.g. in the morning. This makes it ideal, for example, for use in retirement homes or hospitals.

The GEZE Boxer 2-4 or 3-6 is used on the passive leaf – depending on the door leaf width. The integrated closing sequence control is realised by the GEZE Boxer ISM guide rail.
